When you're eight years old it doesn't take much imagination for a cardboard tube on the end of your arm to become a missile launcher or a machine gun. But when you're older, it takes a little more convincing. And that's clearly what inspired this inflatable faux minigun.

Besides giving live-action-roleplayers a decidedly unfair nine-barrel advantage, the $30 wearable novelty finally gives your less prominent arm something useful to do. It's perfect for screwing around with your co-workers at lunch, or intimidating the management staff during a meeting. There's really no reason to ever take it off—at least until someone defeats your uber-weapon with a thumbtack.
